Multiplexer: Is a combinational circuit that is

Multiplexer is a combinational circuit that is used to switch either analog, digital or video signals. It is a simple circuit which accepts multiple analog signals or digital data streams and combines into one signal and transmits over a shared medium. This post will discuss about what is Multiplexer , its types, cascading of Multiplexers, Multiplexing techniques, applications, advantages and disadvantages. Learn what a multiplexer is, how it works, and how to design different types of multiplexers using logic gates. A multiplexer is a device that selects one input from multiple sources and sends it to a single output based on control signals. Since a multiplexer allows the transmission of multiple data in a single line, it is preferred for various applications including the following: Telephone network – A multiplexer integrates the multiple audio signals into a single line of transmission in telephone networks. A multiplexer makes it possible for several input signals to share one device or resource , for example, one analog-to-digital converter or one communications transmission medium, instead of having one device per input signal.
